I am watching the today show right now and they are talking about all the different flu strains this year. It seems that the flu vaccine this year is around 50 percent effective this year. As we are leaving for Vegas in a couple of weeks, we are keeping our fingers crossed. There are already several schook systems around us that have closed due to the outbreak. They also said that if you are within 50 feet of someone's cough who is infected, you are in danger. Also( I hate this part too), even if you had a flu shot this year, as we did, after six months another may be necessary. I am keeping my fingers crossed for all of us who have plans for our Vegas trips in the next few weeks....may we all stay healthy..I cringe every time I see a post on here from someone being ill..before, during and after their trip..and there have been quite a few..
